Know before usingCommunity members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit.SwatchOn's supplier status, counts, and trust language describe its own marketplace and can change. They do not independently establish fibre identity, performance, certification validity, mill ownership, production capacity, colour continuity, delivery, duty, or commercial fit. Review samples, test data, current certificates, the contracting entity, order terms, and landed logistics before purchase.A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing.The workflow is not a contract or quality certification; local legal duties and technical review may still apply.

Source and review
What the source establishesThreadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions.SwatchOn's current marketplace page exposes fabrics, trims, and prints, with swatch samples, in-stock catalogue colours, low-order-quantity options, and global logistics support. The page publishes operator-supplied marketplace and supplier counts and labels participating suppliers as verified partners.YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems.The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
